본 발명은 자동차의 키홀 조광장치에 관한 것으로서, 보다 상세히는 야간에 자동차의 도어를 열기 위해 키를 키홀에 근접시킬 때에 도어록세트에 구비시킨 램프가 자동점등되어 키홀의 위치를 표시하여 주는 자동차의 키홀 조광장치에 관한 것이다.The present invention relates to a keyhole dimming device of a vehicle, and more particularly, to a keyhole of a vehicle in which a lamp provided in a door lock set is automatically turned on to display a keyhole when a key is approached to a keyhole to open a vehicle door at night. It relates to a dimmer.

자동차에는 후론트도어쪽에 도어록세트가 구비되며, 이 도어록세트에 마련된 키홀에 키를 정확히 삽입시켜서 돌려야 도어를 잠금상태를 해제할 수 있다.The vehicle is provided with a door lock set on the front door side, and the door can be unlocked only by inserting the key correctly into the keyhole provided in the door lock set.

그런데, 야간에 특히, 조명이 없는 주변이 어두운 곳에서는 도어록세트의 키홀을 찾아 키를 삽입하는 것이 수월치 않게 된다. 또한, 주간이라도 실내주차장의 구석진 어두운 장소에서는 키홀이 잘 보이지 않게 되고, 더욱이 정전시에는 도어의 키홀을 찾기가 더욱 어려웁게 되므로, 사용자의 키를 삽입하기 위하여 키홀을 찾을 때 불편하고 시간이 지체되는 불편하다는 단점이 있었다.However, it is not easy to find a keyhole of the door lock set and insert a key at night, especially in a dark place without lighting. In addition, even in the daytime, the keyhole is hard to be seen in the dark place of the indoor parking lot, and it is more difficult to find the keyhole of the door during a power failure, so it is inconvenient and time consuming when searching for the keyhole to insert the user's key. There was a disadvantage of being uncomfortable.

본 발명은 이와 같은 종래의 단점을 해결하기 위해 제안된 것으로서, 본 발명은 사람의 손이 도어록세트에 근접시키면 램프가 점등으로 키홀의 위치를 표시하도록 함으로써, 키홀을 찾아 키를 삽입하는 시간을 단축시켜 사용자에게 편리함을 제공하려는 목적이 있다.The present invention has been proposed to solve the above-mentioned disadvantages, and the present invention shortens the time for inserting a key by finding a keyhole by displaying the position of the keyhole by turning on a lamp when a human hand approaches the door lock set. The purpose is to provide convenience to the user.

상기한 목적을 달성하기 위한 본 발명에 따르면, 키홀에 인접설치되어 키홀주위의 어두움을 감지하는 광감지센서와, 상기 광감지센서와 인접설치되어 사람손의 접근을 감지하는 열감지센서와, 상기 광감지센서 및 상기 열감지센서의 신호가 입력되는 앤드게이트회로와, 상기 앤드게이트회로의 출력신호에 따라 전류를 통전하는 전류구동회로와, 상기 전류구동회로의 전류공급에 의해 점등되며 키홀에 인접 설치되는 램프로 구성된 것을 특징으로 하는 자동차의 키홀 조광장치가 제공된다.According to the present invention for achieving the above object, a light sensing sensor installed adjacent to the key hole to detect the darkness around the key hole, and a heat sensing sensor installed adjacent to the light sensing sensor to sense the approach of the human hand, and The AND gate circuit to which the signals of the light sensing sensor and the thermal sensor are input, the current driving circuit which energizes the current according to the output signal of the AND gate circuit, and are turned on by the current supply of the current driving circuit and are adjacent to the key hole. There is provided a keyhole dimming device for a vehicle, characterized in that the lamp is installed.

이하, 첨부도면을 참조하여 본 발명의 바람직한 실시예를 더욱 구체적으로 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

제1도는 본 발명에 의한 키홀 조광장치의 회로구성도이고, 제2도는 본 발명에 의한 램프의 설치상태를 보인 사시도이며, 제3도는 본 발명에 의한 램프의 설치상태를 보인 록실린더의 측단면도이다.1 is a circuit configuration diagram of a keyhole dimming apparatus according to the present invention, FIG. 2 is a perspective view showing the installation state of the lamp according to the present invention, and FIG. 3 is a side cross-sectional view of the lock cylinder showing the installation state of the lamp according to the present invention. to be.

제1도에 도시된 바와같이, 야간의 어두운 조도를 감지하기 위하여 설치한 광감지센서(10)와, 사람손의 접근을 열에 의해 감지하는 열감지센서(20)는 곱의 논리를 갖는 앤드게이트회로(30)의 입력단에 접속되고, 상기 앤드게이트회로(30)의 출력단은 전류고동회로(40)의 일예로 사용된 트랜지스터(TR)의 베이스측에 접속되고, 상기 트랜지스터(TR)의 컬렉터측은 배터리전원(B+)에 직결되고, 상기 트랜지스터(TR)의 에미터측은 램프(50)에 접속된다.As shown in FIG. 1, the light sensor 10 installed to detect dark illumination at night and the heat sensor 20 for detecting the approach of a human hand by heat are AND gates having a logic of product. Connected to an input terminal of the circuit 30, an output terminal of the AND gate circuit 30 is connected to a base side of a transistor TR used as an example of the current oscillation circuit 40, and a collector side of the transistor TR Directly connected to the battery power source B +, the emitter side of the transistor TR is connected to the lamp 50.

상기 광감지센서(10)는 포토다이오드와 같은 반도체소자를 사용하고, 상기 열감지센서(20)는 적외선센서를 사용하여 각각 빛과 열의 변화에 의해 입력되는 전원을 통전시키도록 구성하며, 상기 광감지센서(10) 및 열감지센서(20)를 제2도와 제3도에 도시한 바와같이 키홀(3)주변에 각각 설치하는 것이 바람직하다.The optical sensor 10 uses a semiconductor device such as a photodiode, the thermal sensor 20 is configured to energize the power input by the change of light and heat, respectively, using an infrared sensor, the optical Preferably, the sensor 10 and the heat sensor 20 are installed around the keyhole 3 as shown in FIG. 2 and FIG.

또한, 상기 램프(50)도 제3도에 도시한 바와같이 키홀(3)의 형태가 확인되도록 하기 위하여 키홀(3) 유입구에 설치하는 것이 바람직하다.In addition, it is preferable that the lamp 50 is also installed at the inlet of the key hole 3 in order to confirm the shape of the key hole 3 as shown in FIG.

이와같이 구성된 본 발명은 야간이나 지하주차장에서와 같이 키홀(3)이 보이지 않는 주변이 어두운 상태에서 키를 쥔 사람의 손이 접근하게 되면, 광감지센서(10)는 하이신호를, 열감지센서(20)는 하이신호를 앤드게이트회로(30)로 입력하여 앤드게이트회로(30)의 출력신호를 하이레벨로 한다. 이에 따라 전류구동회로(40)의 트랜지스터(TR)는 턴온되어 배터리전원(B+)을 램프(50)로 인가하게 되어 램프(50)는 점등하게 되어 키홀(3)의 위치를 확인할 수 있도록 키홀(3)의 윤곽을 뚜렷히 나타내게 된다.According to the present invention configured as described above, when the hand of a person holding a key approaches in a dark state where the keyhole 3 is not visible, such as at night or in an underground parking lot, the light sensor 10 receives a high signal and a heat sensor. 20 inputs a high signal to the AND gate circuit 30 to bring the output signal of the AND gate circuit 30 to a high level. Accordingly, the transistor TR of the current driving circuit 40 is turned on to apply the battery power B + to the lamp 50 so that the lamp 50 is turned on so that the position of the key hole 3 can be checked. The outline of 3) is clearly shown.

한편, 본 발명은 주간에는 광감지센서(10)에서 로우신호를 출력하게 되므로 사람손이 접근하게 되더라도 앤드게이트회로(30)의 출력신호가 로우레벨이 되며 전류구동회로(40)의 트랜지스터(TR)는 턴오프되고, 이에 따라 램프(50)는 소등상태를 유지하게 되어 필요없는 전력을 소비하지 않게 된다.Meanwhile, the present invention outputs a low signal from the photosensitive sensor 10 during the day, so even if a human hand approaches, the output signal of the AND gate circuit 30 becomes a low level and the transistor TR of the current driving circuit 40. ) Is turned off so that the lamp 50 remains off so that it does not consume unnecessary power.

이상에서 설명한 바와 같이 본 발명은 특히 야간에 키홀주위로 키를 쥔 사람손이 접근시에 사용자가 키홀을 용이하게 찾도록 조명함으로써 쉽게 도어를 열수 있게 되는 효과가 있다.As described above, the present invention has an effect that the door can be easily opened by illuminating the user's hand to find the keyhole easily when the user's hand holding the key around the keyhole at night.
